Thread: how to validate memory allocation

Anyone help me to validate memory allocation using malloc function for the following code

Code:

 int i,j,*page[16],u=0,p;
 int *array1[4];                                                                                                                           

                                                                                                                             
  for(i=0;i<=1;i++)                    
   {
     array1[i] = (int *)malloc(16*sizeof(int));
     printf("\npartition=%u\n",array1[i]);
   }

thanks in advance

What do you mean "validate"? If you want to check whether an allocation succeeded, just check against NULL:

Code:

int *p;
p = malloc(50 * sizeof *p); /* cast is not necessary */
if(p == NULL) { /* oops, the allocation failed */ }

Also, the correct conversion specifier for printing out a pointer is %p, not %u. And here a cast is required to be completely correct, as %p requires a void* (so it follows, of course, that void pointers themselves needn't be cast).

Code:

/* above code, then... */
printf("%p\n", (void *)p);
